1. Some are like seasons, they come and go,
2. Some are like reasons, they come make a change, leave an impact and serve the purpose.
3. There are people who are for lifetime, they are always their with you. FOREVER.

I often ask myself what is the purpose of our lives and I conclude that life's purpose is to be happy. We have no guarantee what will happen in the future, but we live in hope. That's what keeps us going.
